Describe in detail
This equipment according to the present invention comprises at least one (and optimum is more a plurality of) oscillator V.This oscillator can for electromechanics, electromagnetism, hydraulic pressure or the like any kind.
In the following description, we will illustrate the situation of oscillator by the mode of example, and oscillator comprises the post 1 of at least one sensor (piezoelectricity or magnetic force control), and this post only is associated with thick dull and stereotyped 2,3 on thereon each end of opposite end.The post of sensor is positioned at respect to thick dull and stereotyped 2,3 placed in the middle, and with deformable film 4 with its covering.Stube cable 5 is connected to control-signals generator 6 with post 1.
Oscillator V is arranged among cavity or the well W, and for example cement or concrete coupling material 7 is for example injected this well, thereby closely contacts with post 1 on its total length, and also closely contacts with each thick dull and stereotyped apparent surface of 2,3.In order to allow coupling material 7 to be evenly distributed in the space between the thick flat board, one of the back of thick flat board can provide perforation 8.Thick dull and stereotyped 2,3 diameter must fully meet the diameter of cavity or well W to obtain maximum coupled surface area.
In order further to improve coupling and for distribution pressure in the large volume of coupling material 7, the anchorage bar 9 of suitable length can be fixed to thick dull and stereotyped 2,3 periphery.
According to the embodiment of Fig. 5, as shown in the figure, each thick dull and stereotyped 2,3 comprises at least two plate 2a, 2b that are set parallel to each other and connect by anchorage bar 9.In order to improve the coupling with coupling material 7, the outside surface of each plate 2a, 2b and coupling bar 9 preferably has uneven fluctuating, such as groove.As shown in the figure, the liquid L such as oil can be filled in space between the post 1 of deformable tubular film 4 and sensor.
The cement that is used to be coupled must be dry under the condition that does not shrink, to guarantee good coupling.
Be not that oscillator all is imbedded in the monomer long-pending 7 of coupling material, but as described at Fig. 2 a, two volume 7a, 7b that also can be by this material individually with each thick flat board and on every side the rock stratum be coupled respectively.In order to isolate volume 7a, 7b relative to each other, another material 10 is fed between them.Bentonite that just has expansion characteristics in case get wet or materials similar can be used in the space in the middle of filling.For example when those of the mechanical property of coupling material and rock stratum on every side were different, this solution was useful.
Shown in Fig. 2 b, if the surface level of each the thick flat board on this borehole wall is provided with cavity 11, so according to variation, the coupling energy of oscillator and rock stratum accesses improvement.In order to produce this chamber, for example can use suitable drilling tool or explosive.A solution is downwards put into this well with drilling tool or explosive for for example (Fig. 2 c) on the layout points that oscillator buries, bar 12 carries the coil 13 of safety fuse, and these two coils are effectively separated, and are detonated.
According to the embodiment of Fig. 3, this equipment comprise the oscillator that is similar to Fig. 1 or 5 along the spaced several oscillator V1 of well W, V2 ..., Vn.This oscillator is buried in also that (Fig. 1 or Fig. 2 are a) in one or the more a plurality of coupling material 7,10.
Utilize this layout,, and utilize selected time delay sequential activation oscillator, a plurality of oscillator V1 to Vn are connected to generator 6 can obtain the directivity effect by control box 14.
Suitably downwards therefore the vibration signal of emission is exaggerated, the infringement of those that cause propagating in the other direction.Therefore the amplitude of more than first reflection of rock layer surface has reduced significantly, and the instability of this amplitude has infringement to the repeatability of signal.
This triggered time is for example determined by following mode.
Be arranged to seismicrophone R (nautical receiving set, seismoreceiver or the preferably combination of these two acoustic pickups) vertical with the well that holds oscillator basically or on fully little horizontal range, so that the travel-time between each oscillator and this receiver R can be same as the vertical transmission time basically.This receiver is positioned in the well that holds oscillator, and it is connected with processing unit 15 with the collection that for example is arranged in the surface.If several receivers, for example will be selected the darkest one along the well below oscillator location.Also can use the receiver that is provided with on the surface.At first measure the wave propagation time between each oscillator Vi and this receiver R
With the time delay t that is applied on the different oscillator Vi
i(i=1 to n) specifically can pass through relational expression
Derive from these travel-times, wherein K is a constant, and is not that the top that is configured in the oscillator group is configured in its underpart exactly according to receiver R, so ε is+1 or-1.Unit 15 is controlled these time delays by the mode of control box 14 and is applied on the oscillator.
As described at the patented claim FR-0001792 that the applicant applied for, to launch in each unifrequent application at oscillator, time delay shows with the frequency phase shifted version with time correlation formerly by relational expression Φ I=2 π fti.
According to the embodiment of Fig. 4, by with each for example the seismicrophone of seismoreceiver G1 be associated, it is possible that the control sequence of the oscillator of placing in well triggers.Each seismoreceiver for example is fastened to and is assemblied on two supports 16 between the anchorage bar 9.This seismoreceiver is connected with processing unit 15 with collection in the well outside respectively.For trigger delay with respect to any oscillator Vi of first real-time adjustment in this sequence, in time domain or at frequency domain, effective travel-time of the ripple between them can measure by the method for the delay between any measuring-signal, measure by the crosscorrelation that carries out between the signal that produces at seismoreceiver significantly, and this effective travel-time has been considered in the triggering of oscillator Vi.Can carry out this latency measurement by crosscorrelation.To pass to control box 14 by the time delay that processing unit 15 calculates, control box correspondingly postpones each oscillator with respect to first.
The oscillator that comprises single newel 1 has been described.Yet without departing from the spirit of the present invention, a plurality of posts of piezoelectricity sensor can be inserted between two thick dull and stereotyped 2,3.
